Dex-Cool Question
Had to replace the intake gaskets in my Malibu because of this coolant. Is this stuff going to hurt my 06 Impala (3.5)like it did the 3.1 in my Malibu? Or should I just flush out the factory juice and put in good ol' Prestone? Anyone have any experience along these lines?

theres a thing in court about how that chex-dex-mex-cool...ex caused issues. i cannot remember where it is in here but GM pays for the repairs up to like 800 dollars if your vehicles is in the specified year and mileage and type of vehicle. its real specific but yea... if it were me... just to be safe id pump that stuff out an put in prestone or be like my friend and run 100% water lol.

RE: Dex-Cool Question
GM WATER PUMPS AND OTHER COOLING COMPONETS ARE DEGIGNED TO WORK WITH DEXI-COOL. THOSE ITEMS WILL LAST LONGER WIL DEXI-COOL. YOU MUST CHANGE THE RAD CAP EVERY YEAR TO PRVENT ANY AIR FROM ENTERING COOLING SYSTEM . YOU ALSO NEED TO HAVE ANY LEAKS REPAIRED ASAP. AIR MIXING WITH DEXI -COOL CAUSES DEXI SLUDGE. ALSO THE 5 YEARS OR A 150,000 MILES IS FOR IDEA CONTIONS ONLY, IF YOU READ IT IT ACTUALLY SAYS UP TO 150,000
MILES. IF YOU FLUSH THE COOLANT EVERY 2 YEARS OR 24,000 MILES AND REPLACE THE CAP YOU WILL NEVER HAVE DEXI -SLUDGE. IF YOU CHANGE TO GREEN COOLANT YOU WILL MOST LIKELY HAVE PREMATURE FAILURE. IT IS UNLIKELY THAT DEXI-COOL CAUSED YOUR INTAKE GASKETS TO FAIL. GM HAS HAD MANY PROBLEMS WITH 3.1,3.4 AND 3.8 GASKETS. MANY OF THEM HAVE HAD UPDATED GASKETS / ASSEMBLY PROCEDURES. |
RE: Dex-Cool Question
Thanks for the advice MD. Was thinking of using the Prestone "yellow" which says it will mix with the Dex-Cool. Hadn't heard about the replacement of the cap to prevent air infilteration and Dex-slime(crud), but it sure makes sense. And you're right about the Green ethylene. Since I'm an old person, I can remember changing that stuff once a year (for many years) and the newer mixes are surely an improvement. I appreciate your sharing your knowledgeand your candor.
